I have not observed phyllody infected chickpea plants in any genotype under normal sown plantings (sown during November) at Patna (North East plain). The same set of genotypes, when gown under late sown condition (January 1) to study the effects of heat stress, expressed symptoms of phyllody (pale green foliage, bushy appearance and excessive axillary proliferation). It was interesting to note that the intensity across genotypes was variable and more prominent in irrigated than rainfed crop. Plants which were relatively free from phyllody within the genotypes maintained their disease-free condition when progressed from vegetative to reproductive stage. Whether we should conclude from the observations of the last two years that chickpea phyllody is stage-specific, and commonly encountered in heat-stressed, irrigated condition.
I would say it's temperature driven. Rather then stage specific. I suggest to do some studies at different temperature during at least 2-3 stages of crop development to clear the doubts.
@Vimal I have already mentioned that phyllody was not observed in normal sown crop which experiences low temperature during vegetative phase. Actually I am expecting somebody to elaborate the role of excess or deficient soil moisture and day length on the occurrence of phyllody in late sown chickpea crop in North East plains of India.
